This reminfs me on something; I has an issue with some svn clients and
large commits/imports/etc. It turned out to be a bug in the neon library
on the client side, related to tls which was turned on in recent apache
2.2 versions. Disabling TlSv1 on the server side worked around this.
So now I have:
        SSLProtocol all -TLSv1

maybe it would help with this problem too ?
